INFRARED EMISSIVITIES OF ARCTIC LAND COVER TYPES

This letter describes a field investigation of the thermal infrared (8 -14 mum) emissivities at normal incidence of a number of land cover ty pes typical of the Arctic during summer. The types studied include wat er, various forms of ice and snow, fine shale particles from moraines, and sandstone. The results should assist the interpretation of therma l infrared imagery (e.g. from the infrared channels of the ERS-1 along -track scanning radiometer (ATSR)) of Arctic areas.
